Title
(EN) A DEMAND VALVE RESTRICTOR
(FR) RESTRICTEUR DE SOUPAPE DE DEMANDE
Abstract
(EN)
A demand valve restrictor (1) co-operable with a demand valve for respiratory devices (3) comprising a damping plate (5) having a calibration opening (6) and a respiration opening (7) for controlled air flow through the restrictor (1) and a seal mechanism (4) attached to the damping plate (5) movable between a calibration setting allowing damped air flow through the calibration opening (6) and a patient setting allowing uninterrupted air flow through the respiration opening (7).
(FR)
L'invention concerne un restricteur de soupape de demande (1) qui fonctionne conjointement avec une soupape de demande pour des dispositifs respiratoires (3) comprenant une plaque d'amortissement (5) ayant une ouverture d'étalonnage (6) et une ouverture de respiration (7) pour réguler l'écoulement d'air à travers le restricteur (1), et un mécanisme d'étanchéité (4) fixé à la plaque d'amortissement (5) qui peut être paramétré selon un réglage d'étalonnage permettant un écoulement d'air régulé à travers l'ouverture d'étalonnage (6) ou un réglage patient permettant un écoulement d'air ininterrompu à travers l'ouverture de respiration (7).
